assignor to Hazel-Atlas Glass Co., Wheeling, W. Va., a cox'- poration of West Virginia Application May 13, 1932, Serial No. 611,181 s claims. (ci. cis-43)' 'This invention relates to metallic screw caps for bottles and jars and is directed especially to the reduction in cost of caps of the type in which van outer plain shell is employed to give the ap# 5 pearance of a molded cap.

Another object of the inventionresides in pro' viding a more intimate connection between the outer shell and the inner threaded member, to eliminate any possibility of relative movement between these parts.

Other objects and advantages of the invention Will be apparent from the following description when considered in connection with the accompanying drawing; in which,

Figure 1 is aside elevational view of the completed cap.

Figure 2 is a vertical sectional view through the cap of Figure 1. I Y Figure 3 is a vertical sectional view through the inner band Figure 4 is a horizontal sectional view taken on line 4 4 of Figure 2; and

Figures 5 and 6 arevertical sectional views taken on lines 5-5 and 6 6,v respectively, of

Figure 2;

More specifically, the completed cap, which is referred to by the numeral 1, comprises an outer shell 2, an inner band 3, and a conventional -liner 4.

'I'he outer shell is of cap shape and consists of a top, and a-skirt portion 5. The inner band 3 is rolled from a iiat strip into circular shape and is provided with a screw thread or similar attachy ing means 6. The inner band 3 has an outercir-v cumference slightly less than the inner circumference of the skirt of the outer shell, whereby normally the ends oi the band are slightly spaced, as indicated by numeral?, thus permitting the y assembling of the parts in spite of minor inaccuracies in their fabrication.

It will be understood that any relative movement between the outer 4shell and band would render the caps entirely useless, and to eliminate this possibility a positive lock between the two parts is provided. For this purpose the lower` edge of the inner band -2 is provided with one or more notches 8. Into these notches 8 a por` tion 10 of the ange 9 is pressed when this ange is spun over-the edge voi! the inner band3. This construction is shown more clearly in Figures 2, 4 and 5 and obviously provides a positive safeguard against slippage between the shell and the threaded band.

From the foregoing description and attached drawing it will be seen that I have provided a `screw cap formed of sheet metal in which the exterior surface of the completed cap is entirely smooth in simulation of a molded cap; that the amount of metal employed in such caps is substantially reduced; and that the interlocking connection between the outer shell and inner band avoids any liability of relative rotary movement between these parts.

In accordance with the patent statutes I have invention, but obviously various changes may be made without departing from the spirit of the invention,and all such changes are intended to be included within the scope of` the appended claims. j

What I claim is:

`1. A screw cap closure for bottles and the like including a smooth outer shell comprising a top and a skirt, an inner band formed from a nat strip and provided with thread-engaging means,

edge of the inner shelLand portions of said angebeing seated in said notches.

3. A screw capclosure for bottles and the like .including a smooth outer shell comprising a top and a skirt, an inner` member provided with thread-engaging means and having a-notch adjacent its lower edge, an inturnedflange for securing the parts together, and af portion of the flange seated in said notch;
